The grizzled Sergeant with 20 years in the service may freeze up, the hard-charging LT might start spraying wildly.
Does that happen to veteran sergeants too who had seen more combat. No offense to anyone but seargeants today had probably seen much less combat then the ww2, Korea and Vietnam generations. Did the same thing happen to seargents who were veterans of bloody and long conflicts like WW2 and Vietnam?
I know the US had been in Iraq and Afghanistan for long but as far as i know battles like the ones fought in ww2 are rare. Its more hit and run.
